TOPEKA, Kansas (AP) – The names of two Topeka police officers who were shot to death last year are now displayed on the National Law Enforcement Officers Memorial in Washington, D.C.

Family members of officer Jeff Atherly and Cpl. David Gogian were among those attending ceremonies Monday when the names of 321 U.S. law enforcement officers were formally dedicated on the walls of the memorial.

Topeka Police Chief Ron Miller also attended the vigil.

The officers were killed last December at a Topeka grocery store while investigating a report of suspicious activity. Other officers later shot and killed the suspect, 22-year-old David Tiscareno.
